Still waiting for my life to have background music, but I guess this isn't a shabby start.
A new concept headphone technology could create a “sound version of "#Google Maps” with people able to replay conversations, music and ambient noise from their past. The idea? You could revisit a location many years later and hear once again what you heard in the past. All sounds are geo-tagged to a location and playback starts automatically when someone wearing the earbuds enters a certain area.
